Abstract: The announcement on March 15/16, 2025, of the apparent detection beneath Giza’s Second Pyramid, the pyramid of Khafre, of a whole series of megastructures has caused a viral sensation. The claims made by the Italy-based Khafre SAR Project are so fantastic that it was felt necessary to catalogue what has been released into the public domain, examine the reaction of the outside world, and comment on the suspected methodology behind the published results. Although important to remain sceptical towards these claims—achieved using a unique interpretation of Synthetic Aperture Radar (SAR) data—their potential connection with Giza’s cave underworld and parallels with ancient Egyptian cosmogonic myths seems important to discuss. We look also at the potential time frame of construction of any confirmed underground structures at Giza and speculate on a possible connection with Anatolia’s post-ice age Taş Tepeler culture.

Over the weekend of March 15/16, 2025, a press conference was held at the Castel San Pietro Terme in Bologna, Italy, the ramifications of which would change everything we thought we knew about the origins of ancient Egypt. A team of researchers led by Professor Corrado Malanga from the University of Pisa, Professor Filippo Biondi with the University of Strathclyde, Scotland, and ancient mysteries author Armando Mei announced their detection of a whole series of megastructures existing beneath the plateau at Giza. 1
Using open-source Synthetic Aperture Radar (SAR) data provided by Capella Space and Umbra, and derived from satellites in orbit around 400 miles above the earth’s surface, the team say they have been able to identify the presence of various unique features both within Giza’s Second Pyramid and, more interestingly, beneath it.
Inside the pyramid, they have detected five vertical spaces similar in appearance to the Relieving Chambers above the King’s Chamber inside the Great Pyramid. These structures, described by the team as “djed” columns, like those seen in ancient Egyptian art representing the backbone of the god Osiris, are evenly spaced out within the base of the Second Pyramid.
Underneath the pyramid, the team have determined the presence of what they say are eight hollow cylindrical tubes or wells that penetrate the bedrock for a depth of 648 metres (0.4 of a mile), with a spiralling pathway around each one. These vertical pipes are positioned in two rows of four, which their SAR-based images indicate are oriented north-south. At their termination, the shafts converge into two large cubic chambers, four into one and the remaining four into the other. Each of these chambers has an estimated size of approximately 80 metres (262 feet).
Further structures apparently go off in different directions, leading to the team’s strong belief that beneath the pyramid field is a possible underground city. They identify this with the concept of the Halls of Amenti, the otherworldly destination of the deceased following their passage through a cave-like realm known as the duat.
